Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74LVC841APW,118 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Logic Type: D-Type Transparent Latch with identical 10:10 circuit configuration
• Output Type: Tri-State output capability
• Package / Case: 24-TSSOP surface mount package with matching 0.173" width and 4.40mm dimensions
• Output Current Capability: 24mA for both high and low states
• RoHS Compliance: ROHS3 Compliant status
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The substitute parts listed below meet all these core compatibility criteria. Variations in supply voltage range, propagation delay, and operating temperature represent acceptable engineering tolerances within the 74LVC logic family specifications.

Parameter Comparison

Engineering Selection Recommendations

Both Texas Instruments substitute parts (SN74LVC841APW and SN74LVC841APWR) are active production components with full ROHS3 compliance and MSL 1 rating, making them suitable replacements for the obsolete NXP 74LVC841APW,118.

The SN74LVC841APWR variant is supplied in Tape & Reel (TR) packaging with significantly higher inventory availability (18,130 pcs), making it the preferred choice for high-volume production and long-term supply chain stability. The SN74LVC841APW variant is supplied in Tube packaging with lower inventory levels (771 pcs) and is suitable for lower-volume applications or prototype development.

Both Texas Instruments parts support an extended lower supply voltage limit of 1.65V compared to the NXP original specification of 2.7V, providing additional design flexibility. The propagation delay specification of 2.7ns for Texas Instruments parts is within acceptable engineering tolerances for 74LVC logic family applications. Operating temperature range is reduced to -40°C to 85°C for Texas Instruments parts, which remains suitable for standard industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC841APW and SN74LVC841APWR be used interchangeably with 74LVC841APW,118?

A: Yes. Both Texas Instruments parts are pin-compatible and functionally equivalent. The primary difference is packaging format: SN74LVC841APW uses Tube packaging while SN74LVC841APWR uses Tape & Reel packaging. Selection depends on production volume and supply chain requirements.

Q: What is the significance of the different supply voltage ranges?

A: The NXP original specifies 2.7V to 3.6V, while Texas Instruments substitutes specify 1.65V to 3.6V. The Texas Instruments parts support lower voltage operation, which is beneficial for battery-powered or low-power applications. Designs operating within the 2.7V to 3.6V range are fully compatible with both options.

Q: How does the propagation delay difference affect circuit performance?

A: The NXP original has 1.5ns propagation delay while Texas Instruments parts have 2.7ns. This 1.2ns difference is within standard 74LVC logic family tolerances and does not affect functional compatibility in typical latch applications. Critical timing applications should verify this specification against system requirements.

Q: Are there any temperature range limitations with the substitute parts?

A: The Texas Instruments substitutes operate from -40°C to 85°C, compared to the NXP original's -40°C to 125°C. For applications requiring operation above 85°C, the original NXP part specification must be maintained. Standard industrial and commercial applications operating within -40°C to 85°C are fully supported.

Q: What packaging considerations apply when switching from 74LVC841APW,118 to substitute parts?

A: All three parts use identical 24-TSSOP surface mount packaging with 0.173" width and 4.40mm dimensions. PCB footprints and assembly processes require no modification. Packaging format differences (Tube vs. Tape & Reel) affect only supply chain and production handling, not circuit board integration.
